MACHINE FOR INSERTING COTTON IN CIGARETTE-WRAPPER TUB E S.

v SPECIFICATION forming part of Letters Patent No. 768,238, dated August 23, 1904:.

Application filed April 1, 1902. Serial No. 100,975. (No model.) I

To all whom it may concern:

Be it known that I, SRUL DAVID S. RAKo-. WITZKY, a subject of the Emperor of Russia, re-.

siding in Vilna, Russia, have invented certain new and useful Improvements in Machines'for Inserting Cotton in Cigarette-VVrapperTubes, of which the following is a full, clear, and exact description, reference being had'to the. accompanying drawings, forming a part of this specification.

My invention has for its object to produce a machine which inserts into cigarette-wrapper tubes cotton or similar material, which acts to obstruct the escapeof. the tobacco from 5 the end of the cigarette which is placed in the mouth and also absorbs the nicotine of the tobacco.

My invention consists in the various combinations of devices hereinafter fully described,

and pointed out in the claims.

In order that my invention may be readily understood and carried into effect, I will describe the same fully in reference to the accompanying drawings, in which 5 Figure 1 is a plan view of the machine containing my invention. Fig. 2 is a side elevation of the same. Fig. 3 is an end elevation of the same, partly in-section; and Fig. 4: is a vertical'section, looking from the left from 3 Fig. 1, through the clamps and part of the trough to be described.

1 is a rod which is reciprocated in any desired manner. It carries a depending arm 2, connected by a two-part rod 3, capable of adjustment, with a levert, pivotedat 5 to a stirrup 6, secured to the bed-plate 7 of the mach-inc. j v The upper end 8 of thelever 4 is provided with a wrist-pin 9, which. works in the'open-' 4 ing of a fork 10, depending from a plate 11', secured to a reciprocating slide 12, working in a head 13 on the bed-plate 7 of the machine; This plate 11 is provided with a cam-groove 14:, into which projects a wrist-pin 15 on the end .of one member, 16, of a pair of shears,

such member being pivoted at 17 to an arm" secured to the bed of the machine. The other member, 18, of the shears is secured to the bed of the'machine. The two members are pressed together by a spring 19, the pressure 5 of which can be adjusted bya nut. Secured to the platen is a horizontal plate 20, having a' cam-groove 21, into which a wrist-pin 22 projects. This wrist-pin is secured to a reciprocating slide 23, moving in a head 24, se-

cured to the bed of the machine. Tothe slide 23 is secured, by a bent arm 25, a trough 26, which reciprocates with the slide 23. The sides of thistrough are gradually bent round towardthe front end at 27, as shown, while at its rear end at 28 it is broadened out or funnel-shaped to enable the sliver of cotton to readily pass on to the trough. Placed under this end 28 is a receptacle 29, sustained from the bed of the machine to support the sliver of; cotton fed to the machine. To the 'bent arm '25 is secured a spring 30 over the trough 26', the freeend of which spring is 37 of this bell-crank lever has a slot 38, into which a'wrist pin 39 projects, which is connected to the reciprocating slide 31, to which the bifurcated rod 32 is secured. In front of the shears 16 18 is a pair of clamps, one member, 40,- being stationary, whilethe other 5 member, 41, is movable. The movable member 11 is secured adjustably'to a lever 42, pivoted at 413 to a projection on the main bed of the machine. A spring 4A draws the movable member 41 toward the stationary memher 40 when permitted to do so by the revolving cam 15 on the shaft 16, said cam raising the lever 42,and with it the clamp 11, at the appropriate time.

Directly in front of the path of movement of the bifurcated rod 32 is a V-shaped head 176, having a perforation 48 to permit such bifurcated rod to force the cotton therethrou gh into the end of the wrapper-tube which lies within the V-shaped head at this time. This V-shaped head, the cylinder 68, and the table 62 are parts of a machine for making cigarette wrapper tubes with mouthpieces. (Shown and fully described in United States Letters Patent No. 7 21,087 dated February 17 1903.) In this machine wrapper-tubes are delivered upon the table 62 and advanced until their ends are opposite the V-shaped head 176, when a mouthpiece is introduced, pushing the wrappeetube into the V-shaped recess. time.

In my present machine the wrapper-tube can in this way be moved into position and held opposite the aperture 48 while the bifurcated rod 32 introduces the cotton into it. Such tube can, however, be fed into position and be held for such introduction of the cotton in various ways. i

The operation of the machine is as follows: A sliver of cotton of a suitable diameter is led from a coil of the same in the receptacle 29, over the funnel shaped end 28 of the trough 26, under the bifurcated spring 30, and under the bent-over sides at 27 of such trough, projecting far enough to be caught and held by the clamps 4O 41. On the reciprocation of the rod 1 to the left the lever 4, through the adjustable rod 3, is vibrated, and through its wrist-pin 9, resting in the fork of slide 12, the latter is moved to the right and with it the plate 20, whose cam-groove 21 moves the slide 23 to the rear and with it the trough 26 and bifurcated spring 30, the sliver of cotton during this operation being held by the clamps 4O 41 and the spring 30 slipping over it until the end 27 of the trough is moved far enough back of the shears 16 18 to leave the proper length of cotton to be advanced between the clamps 40 41 on the next movement of the trough to the front. The trough then remains stationary for a short time, due to the dwell of the cam 21. At the same time the-plate 11 has moved the slide 12, carrying the plate 11, to the right until the cam-groove 14, acting on the pin of the movable member 16 of the shears, causes the latter to cut off a short piece of the sliver of cotton at the time the trough 26 has moved far enough to leave the desired length just referred to. At the time the shears have cut off such piece the bifurcated rod 32 (which has been moved to the right by its slide 31 through the bellcrank lever 33 37, pivoted to the lever 4, and the cam-groove 35, acting on the short end of such lever) in its further movement to the right catches the piece of cotton cut off and lying in its path as it is released by the raising of the clamp 41 by the cam 45 and pushes it through the aperture 48 (thus doubling it over) into the Lwrapper-tube held as before The wrapper-tube is thus held a short described. On the movement of the rod 1 to the right the bifurcated rod 32 is moved to the left, as is the slide 12, and with it the plates 11 and 20, the cam-groove 14 of the former raising the movable member 16 of the shears, while the cam-groove 21 of the plate moves the slide 23 to the front and with it the trough 26, the spring catching the sliver of cotton and advancing it between the shears 16 and 18 and the clamps 4t) and 11, when the movable member41 clamps it against the stationary member through the spring 44 acting on the lever 42 when the low part of the cam in revolving is under such lever. Another wrapper-tube having been placed in position in front of the perforation 4a the series of operations tirst described is then repeated.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
